The First Step: Determining Your Battery Type

Before beginning, ensure that you’re following the instructions for the type of battery you have. The majority of Rad bike models use either one of these batteries and both able to be removed from the bike. One has a key port on its battery, however. If your Rad Power Bikes battery is unlike these two types, some helpful tips under “Checking for obvious fixes” may still apply.

The Semi-Integrated Battery has the key lock on the frame of the bike, not on the battery. The Standard Battery Pack, on the other hand, has the key lock on the battery itself. If you have one of these two types of batteries, read on.

Checking for Obvious Fixes

Use this list of reminders to check for any easily-fixable problems:

  1. The battery key must be in the ON position to check the charge level of the battery. If it’s not in that position, then the charge level lights will not come on. This is for the standard battery pack only.
  2. Is your wall outlet not working? To check whether the issue is with the outlet or another object, try plugging in another device. If that won’t power up either, the problem is with your receptacle, not the bike or the battery.
  3. The ideal temperature for charging batteries is between 50 °F–77 °F (10 °C–25 °C). This is known as the Goldilocks zone where it is neither too hot nor too cold. If you’re outside of that range, try and find a location within it to charge again. Remember to also give your battery some time to reach this optimal temperature zone. If the bike was left out in the heat or the cold, it will take some time to adjust after you bring it indoors.
  4. After you use the battery, are you charging it immediately? Some batteries that have recently been used may not start charging as soon as they’re plugged in. It’s okay to plug in the charger right away, but it may take a few minutes for the charger to start working. The battery needs to cool down first. Just be patient.
  5. Are your charger cords not working as intended? Check to see if the connections are loose and need to be fully seated.
  6. Batteries may take 7-8 hours to achieve a full charge. If the battery isn’t full, you might just need to give it more time.
  7. Use an official Rad charger when adding a charge your battery for the best results. The explanations below explain what each light on the chargers means.
  8. A solid red light indicates that the charger is working normally and that your battery is being charged. Some batteries have one light, while others have two. Either way, a solid red light is a good sign.
  9. If your battery has two lights, and one is solid red while the other is solid green, that means your battery has reached full charge. If it only has one light, and it is green, that’s a go signal for you as well.

How to Troubleshoot Problems with an External Standard Battery

Try the tips below to figure out the issue. If you can’t find a solution with these ideas, then review the battery instructions in your bike’s Owner’s Manual.

Situation 1

What is happening: If you charge the battery and then press the Charge Level button, none of the lights stay illuminated. They briefly flicker red before turning off.

What you should do: You will not be able to check the battery level unless the key is turned to the ON position. Turn it to ON and try again. Try this:

  1. Insert your key in the battery key lock.
  2. Turn the key to the ON position.
  3. Press the Charge Level button and check to make sure it is charging properly.

Situation 2

What is happening: If you press the Charge Level button on the battery, you observe 3 green lights and 1 red light.

What you should do: You may not think it at first, but seeing 3 green lights and 1 red light on the Standard External battery indicates a full charge! You don’t need to do anything!

Situation 3

What is happening: The charger’s indicator light is not red, or, for chargers with two lights, neither light is red. And, no lights turn on when you press the battery Charge Level button.

What you should do: The Standard External Battery may have a blown fuse – but don’t worry! These fuses are cheap and easily attainable from any local auto store. Plus, replacing the battery is easy to do yourself by following these simple steps in the owner’s manual under battery fuse replacement.

Get Back Out On the Road

The three situations described above represent the most common problems with external standard batteries.

If your battery isn’t charging, try checking to see if the connections are loose and need to be fully seated. If your charger cords aren’t working as intended, make sure the connections are fully seated. Batteries may take 7-8 hours to achieve a full charge, so be patient. Use a Rad charger for the best results.

If none of these solutions work, then the battery may have a blown fuse and need to be replaced.

We hope this helpful guide gets you back out and enjoying your Rad power bike quickly.
